TO ALL WHOM IT MAY GONCERN:

Be it known that I, CHARLES G. MILLER, of Springfield, in tho county of Cla-rk, and State of Ohio,`ha.ve invented a new and useful Improvement in I-Iarvesters; and Ido hercby'declare/the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a plan view ofi my machine. A i

` Figure 2 isan elevation of the inner side of Vthe frame on the line z :z: of iig. 1.

'Figure' 3 is a rear elevation of the rake-guide and frame.- l

That others may understand the construction and operation of my invention, I will particularly describe it.

The mainframe A is 'made of cast iron, and is mounted upon the axle'of the main Wheels B B which passes` Mbeneath said frame, and ifs-secured thereto by suitable boxes, which are not shown in thedrawings. l -Thctongue C is secured to the front end of this frame by a hinge joint, and may be rendered flexible or rigid at will by key and stop. A beam, D, is secured by bolts to the upper side of theframe A, and projects backward therefrom beyond the rear edge of the platform E, upon which the grain falls as it is severed by the cutters F. The frame G is also secured to the rear edge of the frame A, though, if desirable, it may be cast as apart of said frame. To the outer side of theplati'orm is secured the beam H, which projects backwarduntil its rear end is opposite the rear end ofthe bean D; and 'connecting the rear ends of the beams D and H is the strip I, `which not only maintains the said beams in proper position in regard to each other, but it forms a part of the guideframe of the rake J, which moves back and forth across the platform from side to side, sweeping the grain sideways therefrom, so'as to leavesl clear space for the team at the neigt round. The-rake-head moves back` and-forth upon the guide-rod K, andis actuated by the endless open-link chain L, the rake-head being connected to said chain, first on one part, and then the other, as it reaches one or the other end of its stroke, The plate M is centred upon the end of the main axle, and to it are attached the cutting apparatus, the crankshaft, and thev driving-pinion in such a way that while the horizontal'ity of the main frame is unchanged' the angle of the cutters to the ground may be changed, and they may be adjusted to cut either high o r low, and

the outer end of the cutting apparatus may rise and fall with the undulations of-the ground over `which the machine is being drawn. The-reel N is Vmounted upon the reel-shaft O, which has its bearingsin the brackets P P, upon which the l drivers seat R also rests. Motion to` the various parts of the machinery is communi*- cated from the bearing-wheels B B. i l

Having now indicated in general terms the features of my machine, I will particularly describe such of its parts as may be necessary to obtain a clear understanding of my invention. x p

The cutting apparatus is attached to the plate M through the medium of the arm Q, which is rigidly attached to the inner shoe and the adjustable block S. The' arm Q is pivoted tothe block S by the bolt T, `and upon this bolt, as a.' centre, the outer end of the euttngapp'aratus may rise'and fall-With the uudulations of theground over which it is drawn. "The block S Ais secured to the plate M by two screw-holts, U V, or their equivalents. The bolts U V are adjustable by shifting into dilferent ones of the series of holes in the plate M, so as to shift either the top or the bottom of the block S forward or backward, giving the points ofthe guard-fingers a greater or less inclinatibn to the surface of the ground, as may be desired. Graduations `are marked upon the up; er edge of the plate M for the purpose of facilitating this adjustment of the block S. If deemed preferable, the holt V may pass through a slot in the plate M. In front of theiaxes ofthe main wheels is an arc, W, secured to the steady-bar X, which supports the outer end of the main axle against the lateral strains of the operations of thecntting'apparatus. The plate Mis clamped to the` are W at any desired point by the screiv-bolt Y, and thecntting apparatus is thus raised or lowered to cause the cutters to operate fat i from or near to the surface of the ground. The outer end of the cutting apparatus is supported byan adjust able caster grainlwheel, constructed" and' adjusted with a movable collar, which is fitted to and clamped upon@ the Shank of the wneeharm at any point, as shown in fig. 6. The platform is rectangular, and is connected to the finger-bar by hooks or other convenient means. The front end of the inner shoe is connected to the front end of the mainframe A by a rod anflsorew connection, so that its length may be regulated by said screw to correspond with the'position of the cutting apparatus in respect to the ground, Thev cutters orankfshaft a is Secured by suitable bearings to the inner side of the plate M. Its axis is parallel with the surface of said plate, and at its front end is a crank or eccentric to operate the cutters pitman, and at its rearV end a pinion, b, which is driven by a geared ring, e, upon the outer side of the beering-wheelinearest the cutting apparatus. By this arrangement of parts I am enabled to use. a very short crankshaft, to drive it directly from the drivingwheel, and to place my cutting apparatus opposite the centro of my bearing`-wheels. The Apinion b is loose .n

upon the shaft a, but is provided with 'a clutch-pin, to which it is brought by the clutch-lever d. When the pinion b is thrown out of connection with the shaft a it is also out of gear with the gear-ring c. l

.The reci belongs to the class known as overhung, and open-head. Its shaft O is provided with a pulley, e, over which and a corresponding pulley on the main shaft a band is placed, which communicates motion from the main wheel to the reel. My reel is so constructed that it may be expanded or contracted, as may be found desirable, so as to sweep nearer or further from the cutting apparatus. This is effected by the following devices: The arms fff are pivotcd at one enditothe xed head g, and at the other end to blades N of the reel. The head g is xed upon the reel-shaft at some distance from the end, thereof, and the movable head h is placed near to the end of the shaft. The head h is connected to the arms ff by the short arms z'z'z', so that,

as the head t is drawn nearer to or further from thc end of thc shaft O, the arms ff will be correspondingly affected; and this movement of the head h is efectcd and controlled by a small pinion, 7c, set inthe said head, and a rack, Z, secured to the shaft, as clearly shown in g. 1. The' segments 'm serve to-secure the adjustment of the blades of the reel N parallel with each other, and the set-screw n'secures the head i against any movement not desired by the attendant. i

The rake is a reciprocating rake, moving in a line parallel with the -finger-bar, and sweeping the grain sideways from the platform. The rake-arm o is hung upon the travelling-carriage2),'which moves back and forth upon the rod K and bar I. That part ofthe carriagep through which the vrod K passesis formed with a hub at each cud, upon-which arciitted a shifter, q, anda weighted lever, r, and the rake-arm o. Below the carriage p is the forked standard s, which rides upon the bar I, and over the upper' surface, but confined between the perpendicular walls o'f-thesaid carriage, passes the endless chain L', which is moved by the spur-i wheel t at the rear end of the timber D. 4The chain L moves the carriage p and the rake J back and forth in its reeiprocations in the following manner: Between the parts of thc chain L where it passesov'er the carriage p is the sliding-latch u, which is pointed at both ends, and engages with the links of the chain L on whichever side it is thrown. The shifter q is provided with a point, which is inserted in a hole in the upper surface of this latch, and two arms, one of which is bent so as to project underneath the rake-arm o, and be depressed thereby when the rake drops upon the platform. This depression causes the latch to engage with that part of the chain which is furthest to the rear, andthe carri-age p immediately commences to move toward the Vside of the platform nearest the main frame. The other, arm of the shifter` projects horizontally backward,

and is depressed by the falling of the weighted lever r upon -it, so that the latch u then engages with the opposite part of the chain, and the motion of the carriagep is reversed. This lshifting of the latch from one side to the other can only take place when the rake has reached one or the: other end of its stroke, as follows: The rake-arm ois cont-inued backward beyond the hub upon which'it moves, and forms the curved arm n, and secured to the beam D is the spring-bar or latch w, which projects along and just above the bar I', and Aat the outer end curves slightly backward. At each-end of the bar I, and in its upper edgeis a notch, As the rake is drawn along the-platform, sweeping the grain therefrom, and after the gave] has reached the edge thereof, the arm v comes in contact with the bar w, and as the movement of the rake continues it is forced to rise up until the end of the arm c has passed through the notch x in that end of the bar I. The barwhas been forced tofyield a little in permitting the arm n to pass through the notch x, and when therake-arm has risen high enough to carry the weight at the cud of the lever 1 past a line perpendicular to its centre of motion it falls over upon the rear arm of the shifter g, and the'movement of the carriage p is reversed. The arm v is now compelled by the bar tv to engage with the front edge of the bar I, because the elasticity of the bar 'w is suicient to prevent a return of said arm throughthe notch. The 'rake is therefore retained in the position shown in fig. 2 until the other end of the bnr I is reached, when the notch x "there 'made permits the rake to fall again upon the platfllll, Mid this dropping movement -depresses the forward arm of the shifter g, and again reverses the movement of the carriage. The weighted lever r is also thrown forward by the dropping of the rake, and assists in retaining thc rake vupon the platform while moving the gavel. The spur-wheel t is `aetumtedby the pinion y, receiving motion from the gear-wheel z on the main shaft, and transmitting the same through the shaft a and countershaft b, with their bevel-gears, to the spur-wheel t. 'The pinionvy may be thrown in and out of gear with the wheel e and the shaft a by the clutch-lever c. The spring-fingers d cl d" attached to thc beam D receive the gavel as it is swept from theplatform, and, only yielding to the pressure of the rake J, insures :the delivery of the gavel in a mass, and not in a scattered condition, as might otherwise be the case.

The tongue is connected tothe front end of the main frame by a hinge-joint, and is also provided with a key and screw connection, by which it may be rendered rigid, and at any desiredA angle with the main frame. This key and screw connection is formed as-follows: `A screw-bolt, e', flattened at one end, is inserted through a. hole in thel main frame A, and the nut g screwed on from the upper sid'e of said frame. A key, t, is inserted through both tongue and serewhead, as is shown in fig. T, and the tongue is thereby rendered rigid, while at the same time it may be adjusted to any desired angle by raising or depressing the screw. The nut g has 'a cylindrical and a square portion, and is kept in contact with the frame A by the arm z', which also` retains thewrench 7c in place. The position of the wrench 7c may be changed upon the nut g by raising it` from the square tothe cylindrical portion of the said nut, when it maybe moved forward or backward to gain a new hold, andthe wrench will always be found n place, because the arm z" prevents its entire disengagement from the nut. i

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the' plate M, block S, and arm Q, substantially as and for the purpose set forth.

Mounting Ythe cutters, crank-shaft, and driving-pinion upou the coupling-plate M, as and for the purpose set forth. a

The carriage p, in combination with .the rod K, bar I, and endless chain L, all constructed as set forth.
